The reproductive state of wild, free-swimming tiger sharks (Galeocerdo cuvier), was assessed using underwater ultrasonography at a diving site in Fuvahmulah, a Maldivian atoll within the central Indian Ocean. The presence of embryos were observed in 93% of the adult sharks (26/28) and two distinct embryonic size groups were observed within the subset of scanned adult females. The results suggest that the observed dive site functions as a gestation ground and builds upon previous work that emphasizes the importance of dive sites for the collection of biological data for shark conservation and management.

使用高清潜水超声识别中印度洋虎鲨 (Galeocerdo cuvier) 的第一个孕点



野生自由游动的虎鲨 (Galeocerdo cuvier) 在印度洋中部马尔代夫环礁 Fuvahmulah 的一个潜水点使用水下超声检查评估了它们的生殖状态。在 93% 的成年鲨鱼 (26/28) 中观察到胚胎的存在,并且在扫描的成年雌性子集中观察到两个不同的胚胎大小组。结果表明,观察到的潜水地点起到了孕育地的作用,并建立在之前的工作基础上,这些工作强调了潜水地点对于收集生物数据以保护和管理鲨鱼的重要性。
